A trial of body cameras is already under way among some DVSA staff, with roadside workers up first. If successful, this could then be extended to examiners, the agency said.

DVSA chief executive Gareth Llewellyn acknowledged the hard work of DVSA staff and their role in keeping UK roads safe. Announcing the crackdown, he said “our message is clear”.

"I am immensely proud of my colleagues at DVSA, all of whom work incredibly hard to help you stay safe on Britain's roads,” he explained.

“We do not tolerate anyone abusing, threatening or assaulting them. Our message is clear - whatever has happened, don't take it out on our staff. If you do, we'll press for the strongest possible penalties."
